If you double the mass while applying the same net force, acceleration

If you double the mass while applying the same net force, acceleration

• A. It doubles
• B. Remains the same
• C. It halves
• D. Becomes zero

Answer: (C)

Acceleration is determined by F = ma, so a = F/m. If the same net force is applied but the mass doubles, the acceleration becomes a' = F/(2m) = (1/2)(F/m) = a/2. So the acceleration is halved. This reflects the idea that a heavier object resists changes in motion more, so the same push yields less acceleration. If you imagine pushing a cart with twice the weight while pushing with the same effort, you’ll feel the movement start more slowly.
